Here you can see the starting point of the latest M101 - The first image is luminance data and the second is the combined RGB data - This is all pre processing. I thought it would be interesting to see the start and finish point.

On the left hand side is the data from 42x1800s exposures and on the right is 9x1800s - You can see that there's a big difference in noise and also in data quality. Below is a close up comparison of the background between the two lots of data.

This is a target I have wanted to do for years with a longer focal length. This is VDB141 or the Ghost nebula. It is only 5x30m exposures and already in that 2.5 hours the ghost is starting to show.

​This is going to be really long term as I want only the best data and lots of it. Because it's not narrowband data it is very much affected by the moon, so once that is out (however small) then this data will not be added to.
